Strange Behavior of the Earth’s Core and the Ganges After the Earthquake

Scientists have observed something unusual happening in Earth’s inner core. Researchers from the University of Southern California have studied a series of earthquakes that occurred between 1991 and 2023 in the South Sandwich Islands near Antarctica. They analyzed the seismic waves from these earthquakes that passed through the Earth’s interior, including the inner core. The data suggests that around 2008, the Earth’s inner core changed its rotation direction relative to the mantle and began rotating at a speed that is less than half of its previous speed. There is a possibility that the inner core is being deformed by the gravitational pull of the mantle, which accounts for about 70% of Earth’s mass.

An ancient seismic event, about 2,500 years ago, caused significant changes to the main channel of the Ganges River in Bangladesh, one of the world’s largest rivers, and the surrounding landscape. The river has shifted to an entirely new area as a result of this extreme event. Satellite images and chemical analysis of sand and silt have confirmed the old riverbed and indicated that several tremors were of a magnitude of 7 to 8, similar to the earthquake that struck Turkey and Syria in 2023. Bangladesh, with its high population density, is susceptible to major earthquakes. Hence, there is a sobering possibility that within a few hundred to a thousand years, the Ganges River could change its course again due to powerful tremors. This potential scenario requires serious consideration and planning.
